java - What is different between writeBinaryMessage() and write() of Vert.x WebSocket? -


i'm working on server project using vert.x , serverwebsocket class.

currently, project uses pump#pump() , serverwebsocket#write() methods send large binary data clients , works well. found serverwebsocket has method send binary data, writebinarymessage().

the manual says:

writebinarymessage() : data might written multiple frames if exceeds maximum websocket frame size

but think serverwebsocket#write() sends data multiple parts pumping stream.

what difference between writebinarymessage() , write()?

writebinarymessage():

  • writes (potentially large) piece of binary data connection. data might written multiple frames if exceeds maximum websocket frame size.

write()

  • write data stream. data put on internal write queue, , write happens asynchronously. avoid running out of memory putting on write queue, check writestream.writequeuefull() method before writing. done automatically if using pump.

both returns same type of data , takes buffer type of parameter.

only difference both functions handle data internally different.

if want write big binary data, should use writebinarymessage(buffer data) , if send alot small messages dynamically should use async function write(buffer data)
